TAKE- U P ME( .'H AI\lISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 646,614, dated April 3,1900. Application filed January 22, 1900. Serial No. 2,266. (No model.)

To aZZ whom/it may concern:

Be it known that I, HORACE WYMAN, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts,have invented certain new and useful Improvements inTake-Up Mechanism for Looms, of which the following is a specification.

My invention relates to take-up mechanism for looms and to that class oftake-up mechanisms in which the winding-up roll for the wovencloih ispressed upward and yieldingly held against the take-up roll by springsor their equivalent.

The object of my invention is to improve upon this classof take-upmechanisms and provide improved mechanism for releasing the winding-uproll from contact with'the take-up roll to remove the winding-up rollfrom the loom or to release one end only of the winding-up roll toadjust the edge of the cloth at that end of the roll.

My invention consists in certain novel features of construction of mytake-up mechanism, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a front view of a take-upmechanism with my improvements applied thereto looking in the directionof arrow at, Fig. 2. Fig. 2 is a vertical section taken at a pointindicated by line 2 2, Fig. 1, looking in the direction of arrow 1),same figure. Fig. 3 is a vertical section taken at line '3 3, Fig. 1,looking in the direction of arrow and corresponds to Fig. 2, but showsthe opposite position of the windingup-roll-releasing mechanism. Thewindingup roll, the take-up roll, and other 'rolls are not shown in thisfigure. Fig. 4 is a sectional plan. view taken at line 4 4, Fig. 1,looking in the direction of arrow cl and showing the foottreadles of thereleasing mechanism at the right-hand end of the take-up-mechanism shownin Fig. 1.

In the accompanying drawings, the winding-up roll, take-up roll, andother rolls are operated by a system of gears (shown at the right inFig. 1) in the ordinary and well-known way, and therefore the operationdoes not need to be described herein.

The take-up roll 1 is supported at its ends in bearings on stands 2 and3, attached to the winding-up roll 6.

- end of each support 8 is recessed or grooved to receive the journals 6on the ends of the support 8 is pivotally connected to one arm ofangle-levers 9 and 9. The angle-lever 9 is in this instance fast ontheshaft 10 and the angle-lever 9' loose thereon. The shaft 10 isloosely mounted at each end in stands 11, secured to the cross-girth 12of the loom. The other arm of each angle-lever 9 and 9 is connected to arod 13, provided with an adjustable spring 14 and loosely mounted at itsinner end in a stand or bracket 15, attached to the back girth 16 of theloom to have a sliding motion therein. The springs 14 bear at one endagainst the stand and at the other end against an adjusting nut orcollar 17, secured on the rod 13 by a set-screw 18, and act toyieldingly hold the winding-up roll 6 in its upper position and pressedagainst the takeup roll 1 through the angle-levers 9 and 9 andvertically-moving support 8. The shaft 10 has fast upon it at one end-inthis instance the right-hand end, as shown in Fig. 1-a foottreadle 19,projecting toward the front of the loom. Beside the treadle 19 andintegral with the'angle-lever 9, which is loosely mounted on shaft 10,is a second foot-treadle 20. When. the treadle 19 is pressed down by thefoot of the attendant, it will rock the shaft 10 and move down the frontend of the angle-' -lever 9 will also be moved down with it and thesupport 8 at the right-hand end of the 5 The lower end of eachwinding-up roll 6 to release said end from the take-up roll 1. If thetwo treadles I9 and 20 are moved down together, angle-levers 9 and 9will be operated and both ends of the winding-up roll 6 will be loweredsimultaneously.

The stands 2 and 3 are each provided with a projection 21, against whichthe support 8 will rest when in its lowest position and with thejournals (3 of the winding-up roll 6 at the opening in the guideways 7,as shown in Fig. 3, preparatory to the removing of the winding-up roll 6from the loom.

hen the supports 8 are in their lowest position, as above described,they are retained there against the pressure of the springs 14 by thelugs 22 thereon engaging with the projections 21. \Vhen the foot of theattendant depresses the levers 19 and 20 and moves back the winding-uproll 6, so that itsjournals 6 will enter the vertical portion of theguideways 7, the lugs 22 will be disengaged from the projections 21 andthe springs 14 through intermediate connections will act to raise thewinding-up roll 6 into yielding contact with the take-up roll 1 and holdit there, as shown in Fig. 2.

The advantages of my improvements will be readily appreciated by thoseskilled in the art. By my construction I am enabled to lowerindependently either end of the winding-up roll from one side of theloom, or I may lower both ends of the winding-up roll simultaneouslyfrom the same side of the loom. It will be understood that the detailsof the construction of myimprovements may be varied somewhat, ifdesired. In case it is not desired to lower each end of the winding-uproll independently, but to lower both ends simultaneously, only onetreadle may be used, and in such case angle-lever 9 will be fast on theshaft 10. 3y having two springs 14, one for each end of the winding-uproll, I obtaina greater and more uniform pressure against the take-uproll.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In the take-up mechanism of a loom,the combination with fixedvertical guideways on the stands of the take-up mechanism, into whichthe journals on the winding-up roll ex tend and move, and the winding-uproll, of vertically-moving supports for said journals, and means foryieldingly holding said supports, and for depressing them independently,or together, to lower the winding-up roll, substantially as shown anddescribed.

2. In the take-up mechanism of aloom, the combination with fixedvertical guideways on the stands of the take-up mechanism, into whichthe journals on the windingup roll extend and move, and the winding-uproll, of vertically-moving supports for said journals, and means forlowering the supports to release the winding-up roll, consisting of atreadle on a shaft, levers or arms connected with said shaft, and withthe supports, substantially as shown and described.

3. In the take-up mechanism of a loom, the combination with fixedvertical guideways on the stands of the take-up mechanism, into whichthe journals on the winding-up roll extend and move, and the winding-uproll, of vertically-moving supports for said journals, and means foryieldingly holding said supports, consisting of a lever or arm connectedto the lower end of each support, and mounted on a shaft, and saidshaft, and'a second lever or arm, and a rod connected therewith,

and a spring on said rod to actuate the same,

and a treadle fast on the said shaft to rotate the same against theaction of the spring, substantially as shown and described.
